radiator fan controlled by ECM. when temp go over determined value, ECM provide ground to fan circuit. Some system have 2 temp sensors. One for driver information and one for ECM to control rad. fan. make sure you change ECM temp sensor. Also possible open power or ground circuit to rad. fan.Check if wires are OK
